| /* -*- auto-fill -*- */ |
| =============================================================================== |
| Changes for patch v1 |
| |
| - creation of devfs |
| |
| - modified miscellaneous character devices to support devfs |
| =============================================================================== |
| Changes for patch v2 |
| |
| - bug fix with manual inode creation |
| =============================================================================== |
| Changes for patch v3 |
| |
| - bugfixes |
| |
| - documentation improvements |
| |
| - created a couple of scripts (one to save&restore a devfs and the |
| other to set up compatibility symlinks) |
| |
| - devfs support for SCSI discs. New name format is: sd_hHcCiIlL |
| =============================================================================== |
| Changes for patch v4 |
| |
| - bugfix for the directory reading code |
| |
| - bugfix for compilation with kerneld |
| |
| - devfs support for generic hard discs |
| |
| - rationalisation of the various watchdog drivers |
| =============================================================================== |
| Changes for patch v5 |
| |
| - support for mounting directly from entries in the devfs (it doesn't |
| need to be mounted to do this), including the root filesystem. |
| Mounting of swap partitions also works. Hence, now if you set |
| CONFIG_DEVFS_ONLY to 'Y' then you won't be able to access your discs |
| via ordinary device nodes. Naturally, the default is 'N' so that you |
| can still use your old device nodes. If you want to mount from devfs |
| entries, make sure you use: append = "root=/dev/sd_..." in your |
| lilo.conf. It seems LILO looks for the device number (major&minor) |
| and writes that into the kernel image :-( |
| |
| - support for character memory devices (/dev/null, /dev/zero, /dev/full |
| and so on). Thanks to C. Scott Ananian <cananian@alumni.princeton.edu> |
| =============================================================================== |

| /dev/sd/c0b1t2u3 controller=0, bus=1, ID=2, LUN=3, whole disc |
| /dev/sd/c0b1t2u3p4 controller=0, bus=1, ID=2, LUN=3, 4th partition |
| |
| - loop devices now appear in devfs |
| |
| - tty devices, console, serial ports, etc. now appear in devfs |
| Thanks to C. Scott Ananian <cananian@alumni.princeton.edu> |
